Abstract

An aircraft tire has a pair of bead sections, sidewall sections extending from outer side in a radial direction of the bead sections, and a tread section extending between the sidewall sections; the aircraft tire includes an RFID tag having a tag main body (IC chip) configured to store an information about the aircraft tire and an antenna extended from the tag main body, wherein, when a diameter size of the aircraft tire is 15 inches or less, in a tread surface view, the antenna is disposed such that the antenna is parallel to a tire circumferential direction or intersects the tire circumferential direction within a predetermined angle range, and a belt part disposed in the tread section is made of non-metal material.

First claim

The invention claimed is:

1. An aircraft tire having a pair of bead sections, sidewall sections extending from outer side in a radial direction of the bead sections, and a tread section extending between the sidewall sections, the aircraft tire comprising:
a radio frequency identification (RFID) tag that is attached to a tire inner surface of the tread section and includes a tag main body configured to store an information about the aircraft tire and an antenna extended from the tag main body, wherein
a diameter of the aircraft tire is 15 inches or less,
the tag main body and the antenna of the RFID tag is sealed within a rubber patch and the rubber patch is attached to the tire inner surface of the tread section by an adhesive,
the antenna is a monopole antenna or a dipole antenna,
the antenna is disposed such that the antenna is parallel to a tire circumferential direction or intersects the tire circumferential direction within 5 degrees in a tread surface view, and
a belt part disposed in the tread section is made of non-metal material.

2. The aircraft tire according to claim 1 , wherein the monopole antenna or the dipole antenna has a linear shape or wavy line shape.

3. The aircraft tire according to claim 1 , wherein the RFID tag is disposed circumferentially apart from a balance patch provided on the tire inner surface.
